How can I integrate Tomcat with JBoss?

Most of this information comes from the official JBoss site at http://www.jboss.org/business/jboss-tomcat.html

First of all, JBoss has been tested with tomcat 3.2.1, newer version shall be configured in similar way I think.

Tomcat libs must be in classpath; then edit JBOSS_HOME/conf/default/jboss.conf and un-comment ClassPathExtension mbean for the tomcat lib directory to:


<MLET CODE = "org.jboss.util.ClassPathExtension" ARCHIVE="jboss.jar" CODEBASE="../../lib/ext/">
  <ARG TYPE="java.lang.String" VALUE="TOMCAT_HOME/lib/">
  <ARG TYPE="java.lang.String" VALUE="Tomcat">
</MLET>

edit JBOSS_HOME/conf/default/jboss.jcml and uncomment the EmbeddedTomcatService mbean. Locate:

  <mbean code="org.jboss.tomcat.EmbeddedTomcatService" name="DefaultDomain:service=EmbeddedTomcat" />

Always in jboss.jcml, check that J2eeDeployer is:

  <mbean code="org.jboss.deployment.J2eeDeployer" name="J2EE:service=J2eeDeployer">
    <attribute name="DeployerName">Default</attribute>
    <attribute name="JarDeployerName">:service=ContainerFactory</attribute>
    <attribute name="WarDeployerName">:service=EmbeddedTomcat</attribute>
  <mbean>

Add the following lines to TOMCAT_HOME/conf/server.xml


        <ContextInterceptor className="org.jboss.tomcat.ContextClassLoaderInterceptor" />

        <ContextInterceptor className="org.jboss.tomcat.naming.JbossWebXmlReader" />

        <RequestInterceptor className="org.apache.tomcat.request.Jdk12Interceptor" />

        <RequestInterceptor className="org.jboss.tomcat.security.JbossRealm" />

To compile JSP files, add the JDK lib/tools.jar file to the classpath in run.sh/run.bat, or copy tools.jar to the TOMCAT_HOME/lib directory.

Starting JBoss with run.sh/run.bat you should now see the following Tomcat related output in your log messages:
